Mark,
This is easy if you understand the structure of Mathematica expressions.
Try evaluating
myrule=(a->b)
myeqn = Equal@@myrule (or Apply[Equal,myrule])
and you will have turned a rule into an equation. To understand it better,
look at
FullForm[myrule]
FullForm[myeqn]
to see that you just had to change the Head of the expression.
I hope this helps,
